As much as I like(d) Fictionwise and their discount codes, this reinforces the habit of stripping the DRM off of purchased books and putting them somewhere safe. We should not be at the whim of any site or company closing its doors. On the DRM front, we should not be put in a position where, in order to keep something we paid money for, we have to circumvent or possibly be breaking a law. That is just unacceptable.

Ditto! However, stripping and storing/backing up on an external drive or"the cloud" is always a good idea.
